Abstract: A method for implementing NVMe over fabrics includes generating, by a terminal, a NVMe instruction, where the NVMe instruction indicates a data read operation or a data write operation. The method further includes sending, by the terminal by using remote direct memory access (RDMA), the NVMe instruction to a submission queue (SQ) that is stored in a server. When the NVMe instruction indicates the data read operation, the method includes receiving, by the terminal by using the RDMA, to-be-read data sent by the server. Alternatively, when the NVMe instruction indicates the data write operation, the method includes sending, by the terminal, to-be-written data to the server by using the RDMA. The method further includes receiving, by the terminal, an NVMe completion instruction sent by using the RDMA by the server; and writing, by the terminal, the NVMe completion instruction into a completion queue (CQ) that is set in the terminal.

Abstract: A device management method, a device, and a device management controller are provided. The method includes receiving, by a device, a first instruction message sent by a device management controller, determining, by the device according to the first instruction message, a status of current device management information compared with device management information in a previous query period, generating a first feedback message, where the first feedback message indicates the status of the device management information, and sending, by the device, the first feedback message to the device management controller such that the device management controller manages the device according to the first feedback message. The device feeds back to the device management controller only the status of the current device management information compared with the device management information in the previous query period, effectively reducing a transmission amount of device management information.

Abstract: A method, an apparatus, and a communication node for suppressing output noises of peripheral component interconnect express (PCIe) devices in optical fiber communication is provided. The communication node includes a PCIe chip and a detection and control circuit connected to a transmitting end of the PCIe chip. The PCIe chip transmits an electrical signal by a transmitter of a first lane. The detection and control circuit detects a differential-mode voltage of the electrical signal. If the differential-mode voltage is lower than a first threshold, the detection and control circuit controls an optical module connected to the PCIe chip not to transmit an optical signal through the first lane of the optical module. When a PCIe system includes the communication node, output noises of the transmitter is suppressed, and a normal optical fiber communication link is ensured.
